Although an example in which the upper case 201 is rotated with respect to the lower case 301 has been described, the lower case 301 may be rotated with respect to the upper case 201 and the upper case unit 200 and the lower case unit 300 may be assembled.

  Next, with reference to FIGS. 8 and 9, installation work of the surveillance camera 100 on the ceiling or wall surface according to the present embodiment will be described. FIG. 8 is a diagram illustrating a state before the monitoring camera 100 is installed in the present embodiment. FIG. 9 is a diagram illustrating a state after installation of the monitoring camera 100 in the present embodiment. 8 shows a state in which the first case 301 is located at the first release position and the second case 201 is located at the second lock position. FIG. 9 shows the state where the first case 301 is located at the first lock position. In this state, the second case 201 is located at the second lock position.

  In installing the monitoring camera 100, first, the installation member 101 is fixed to the ceiling or the wall surface. Next, as shown in FIG. 8, the lower case unit 300 is arranged with respect to the installation member 101 so that the hook 101 a of the installation member 101 is arranged in the trapezoidal portion 301 c of the lower case unit 300. Then, the lower case unit 300 is rotated in the first direction (A direction in the figure), and as shown in FIG. 9, the hook 101a and the locking portion 301d are engaged.

  In other words, in the state where the second case 201 is located at the second lock position, the first case 301 is moved from the first release position toward the first lock position with respect to the installation member 101 installed on the fixed surface. The surveillance camera 100 is installed on the fixed surface by rotating in the (A direction). Further, when the lower case unit 300 rotates in the A direction, the second protrusion 501c of the rotation restricting portion 500 reaches the indented portion 101b of the installation member 101 and is pressed by the indented portion 101b. When further rotated, the rotation restricting portion 500 of the lower case unit 300 moves along the recessed portion 101 b of the installation member 101. When the second protrusion 501c of the rotation restricting portion 500 is fitted into the through hole 101c of the installation member 101, the second protrusion 501c is disposed in the through hole 101c by the urging force of the urging member 503. Thereby, the movement of the lower case unit 300 in the height direction and the rotation direction is restricted, and the state shown in FIG. 9 is obtained, and the installation of the surveillance camera 100 on the ceiling or wall surface is completed.

  As described above, since the monitoring camera 100 according to the present embodiment can be installed on the ceiling or wall surface by a rotation operation, the load applied to the installation operator is small, and the installation of the monitoring camera 100 on the ceiling or the like is easy.

FIG. 10 shows a state where the first case 301 is located at the first lock position and the second case 201 is located at the second lock position.

  First, the rotation restriction of the upper case unit 200 is released by releasing the fastening of the screw 202 of the upper case unit 200. In this state, the upper case unit 200 is rotated in the second direction (B direction in the figure). At this time, since the protrusion 201d of the upper case unit 200 and the first protrusion 301e of the lower case unit 300 interfere with each other, the rib 201c of the upper case unit 200 is deformed by the amount of interference with the first protrusion 301e. Further, the bias release member 502 of the rotation restricting portion 500 is operated by the second rib 201e formed on the upper case 201.

  Thereby, the 2nd protrusion 501c moves to the direction away from the installation member 101, and the rotation restriction | limiting of the installation member 101 and the lower case unit 300 is cancelled | released. Furthermore, it will be in the state shown in FIG. 10 by rotating in the same direction. When the hook 101a and the locking portion 301d are disengaged from each other by further rotating, the upper case unit 200 and the lower case unit 300 can be integrally removed from the installation member 101.

  In other words, when the first case 301 is in the first lock position and the second case 201 is in the second lock position, the second case 201 is rotated in the second direction (the B direction), which is the opposite direction to the first direction. By moving the first case 301, the first case 301 rotates from the first lock position to the first release position, and the first case 301 and the second case 201 can be detached from the installation member 101 integrally.

  As described above, the surveillance camera 100 according to the present embodiment can remove the upper case 201 and the lower case 301 integrally from the installation member 101 with an easy configuration.

  Next, an operation for removing the upper case unit 200 from the lower case unit 300 will be described with reference to FIGS. FIG. 11 is a diagram illustrating a state in which the upper case unit 200 of the monitoring camera 100 according to the present embodiment is removed. FIG. 11 shows a state in which the first case 301 is located at the first lock position and the second case 201 is located at the second release position.

  First, the rotation restriction of the upper case unit 200 is released by releasing the fastening of the screw 202 of the upper case unit 200. In this state, the upper case unit 200 is rotated in the first direction (C direction in the figure). As a result, as shown in FIG. 11, the engagement state of the first rib 201c of the upper case unit 200 and the first protrusion 301e of the lower case unit 300 is released, and only the upper case unit 200 can be removed from the surveillance camera 100. It becomes. At this time, the engaged state and the rotation restricted state of the lower case unit 300 and the installation member 101 are maintained.

In other words, by rotating the second case 201 in the first direction (C direction) from the second lock position to the second release position with the first case 301 placed at the first lock position, The second case 201 can be detached from the first case 301 with the case 301 fixed to the installation member 101.
As described above, since the surveillance camera 100 according to the present embodiment can be easily removed and only the upper case unit 200 can be removed, the maintenance of the lens barrel unit 400 is performed while the lower case unit 300 remains installed. be able to.

  Further, since the protrusion 201d of the upper case unit 200 and the first protrusion 301e of the lower case unit 300 are rotated in a direction in which they do not come into contact with each other, the rotation is compared with the case where the upper case unit 200 and the lower case unit 300 are integrally removed. The operation torque required for operation is small.

  This allows the operator to recognize the unit to be removed and, for example, when the maintenance is to be performed with the lower case unit 300 installed, the lower case unit 300 and the upper case unit 200 are integrally removed. It becomes possible to suppress.

  Also, the direction in which the upper case unit 200 is rotated when the lower case unit 300 and the upper case unit 200 are integrally removed (direction B), and the direction in which the upper case unit 200 is rotated when only the upper case unit 200 is removed (direction B). C direction) is the reverse direction.

  Thereby, it can suppress that an operator performs incorrect operation.
